By using sound waves to push and pull matter like science fiction tractor beams, scientists have developed "acoustic tweezers" that can manipulate blood cells and microscopic worms on a platform the size of a dime.

During a solar eclipse, the Moon's passage overhead blocks out the majority of the Sun's light and casts a wide swath of the Earth into darkness. The land under the Moon's shadow receives less incoming energy than the surrounding ...

For more than a year, scientists at Oregon State University's Hatfield Marine Science Center deployed a hydrophone in 50 meters of water just off the coast of Newport, Ore., so they could listen to the natural and human-induced ...

(PhysOrg.com) -- Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, ...

Photoacoustic (PA) imaging is a method to visualize structures with optical contrast in biological tissue. Despite the strong optical scattering in tissue, high resolution images in the visible and near infrared spectral ...

Austrian and German researchers at the University of Vienna and Technische Universitaet Muenchen have solved a long-standing problem in the design of mechanical resonators: the numerical prediction of the design-limited damping. ...
